Biologics Before Surgery Are Not Associated With Complications After Surgery for IBD: A National Surgery Quality Improvement Program IBD Collaborative Causal Inference Analysis.
Article in Diseases of the colon and rectum, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe association between preoperative exposure to biologics and postoperative outcomes after surgery for IBD remains controversial.
objectiveWe hypothesized biologic exposure within 60 days of surgery is safe and not associated with an increase in postoperative adverse events.
designMulticenter national cohort. SETTINGS: Twenty-four IBD centers, from 2020 to 2024. PATIENTS: Adult patients from the American College of Surgeons-National Quality Improvement Program IBD Collaborative were included.
main outcome measuresThe primary outcome was adverse event rates within 30 days postoperatively; secondary outcomes included rates of infectious and overall complications. The primary predictor was exposure to biologics within 60 days of surgery. Propensity score-based causal inference modeling was performed. Point estimates were expressed as relative risks with 95% CIs.
resultsA total of 2926 patients were included: 1427 (48.8%) were exposed to biologics and 1499 (51.2%) were not exposed. Preoperatively, the biologic cohort was more likely to have Crohn's disease, be younger, be from high-volume centers (all p < 0.0001), be anemic and malnourished (both p = 0.02), and be exposed to corticosteroids and/or immunomodulators (both p < 0.0001). Intraoperatively, the biologic cohort had shorter operative times, more minimally invasive procedures and partial colectomies, and fewer ileoanal pouches and ileostomies (all p < 0.0001). Inverse probability treatment weighting revealed that biologics were not associated with postoperative infections (0.97; 95% CI, 0.72-1.05), complications (0.92; 95% CI, 0.81-1.04), or adverse events (0.92; 95% CI, 0.83-1.02). Similar results were observed in unadjusted, propensity score-adjusted, and propensity score-matched models. LIMITATIONS: Generalizability, selection bias, unmeasured confounders, and a 60-day window for biologics were the limitations of this study.
conclusionsPreoperative biologic exposure within 60 days of surgery for IBD was not associated with any causal increase in postoperative adverse outcomes. These findings indicate that administration of biologics before IBD surgery is safe and does not increase short-term adverse outcomes. See Video Abstract . LOS PRODUCTOS BIOLGICOS ADMINISTRADOS ANTES DE LA CIRUGA NO SE ASOCIAN CON COMPLICACIONES POSOPERATORIAS TRAS LA CIRUGA PARA LA ENFERMEDAD INFLAMATORIA INTESTINAL ANLISIS DE INFERENCIA CAUSAL COLABORATIVO SOBRE LA ENFERMEDAD INFLAMATORIA INTESTINAL DEL PROGRAMA NACIONAL DE MEJORA DE LA CALIDAD QUIRRGICA: ANTECEDENTES:La relación entre la exposición preoperatoria a productos biológicos y los resultados posoperatorios tras una cirugía por enfermedad inflamatoria intestinal sigue siendo controvertida.Objetivo:Nuestra hipótesis es que la exposición a productos biológicos en los 60 días previos a la cirugía es segura y no se asocia con un aumento de los eventos adversos posoperatorios.Diseño:Cohorte nacional multicéntrica.ENTORNOS:Veinticuatro centros de enfermedad inflamatoria intestinal, 2020-2024.PACIENTES:Pacientes adultos del Programa Nacional de Mejora de la Calidad del Colegio Americano de Cirujanos, Colaboración para la Enfermedad Inflamatoria Intestinal.PRINCIPALES MEDIDAS DE RESULTADOS:El resultado principal fue la tasa de eventos adversos en los 30 días posteriores a la cirugía; los resultados secundarios incluyeron las tasas de complicaciones infecciosas y generales. El predictor principal fue la exposición a productos biológicos en los 60 días previos a la cirugía. Se realizó un modelo de inferencia causal basado en la puntuación de propensión. Las estimaciones puntuales se expresaron como riesgos relativos (RR) con intervalos de confianza del 95%.RESULTADOS:Se incluyó a un total de 2926 pacientes: 1427 (48,8%) expuestos a productos biológicos y 1499 (51,2%) no expuestos. Antes de la operación, la cohorte biológica era más propensa a padecer la enfermedad de Crohn, ser más joven, proceder de centros de gran volumen (todos p < 0,0001), ser anémica y estar desnutrida (ambos p = 0,02) y estar expuesta a corticosteroides y/o inmunomoduladores (ambos p < 0,0001). Durante la intervención, la cohorte biológica tuvo tiempos quirúrgicos más cortos, más procedimientos mínimamente invasivos y colectomías parciales, y menos bolsas ileoanaales e ileostomías (todos p < 0,0001). La ponderación de la probabilidad inversa del tratamiento reveló que los biológicos no se asociaron con infecciones posoperatorias (0,97, 0,72-1,05), complicaciones (0,92, 0,81-1,04) o eventos adversos (0,92, IC del 95%: 0,83-1,02). Se observaron resultados similares en los modelos no ajustados, ajustados por puntuación de propensión y emparejados por puntuación de propensión.LIMITACIONES:Generalización, sesgo de selección, factores de confusión no medidos y ventana de 60 días para los biológicos.CONCLUSIONES:La exposición preoperatoria a productos biológicos en los 60 días previos a la cirugía por enfermedad inflamatoria intestinal no se asoció con ningún aumento causal de los resultados adversos postoperatorios. Estos hallazgos indican que los productos biológicos antes de la cirugía por enfermedad inflamatoria intestinal son seguros y no aumentan los resultados adversos a corto plazo.
